Milling The milling operation consists of the steps of grinding, sifting, classifying, purifying, aspirating and in some case, final drying. The normal flow is through break rolls and then to sifters. The break rolls are followed by reduction roll which grind the endosperm to the desired particle size. 7. WET MILLING PROCESS Corn.
The workpiece's suitability for a dry process also depends on the material. A cutting fluid can be superfluous for cutting most alloys of cast iron, and carbon and alloyed steel, for example. These materials are relatively easy to machine and conduct heat well, allowing the chips to carry away most of the heat generated.
The corn wet milling process uses about 1.1 to 2.0 kg of SO2 per megagram (Mg) of corn (0.06 to 0.11 lb/bu). The SO2 is dissolved in process waters, but its pungent odor is present in the slurries, necessitating the enclosing and venting of the process equipment. Vents can be wet-scrubbed
